i have both the milestone and the n900. i bought the milestone on release last december and it is an excellent phone and once it gets the 2.2 update should be even better god willing. i bought my n900 about 4-5 weeks ago and have using all the time since but for 2 seperate days when i used the milestone. the first thing that hits you going to the milestone from the n900 is the number of apps for it and all the stuff you can do with them and the phone, wheras the n900 is severely limited in this regard although most of the basics are covered.
